Slidably mounted on said support or rod 25 is a pressure device or follower 26 having a hub 2'7 bearing on the rod. A coiled spring 28 surrounds the rod 25 and the hub 27 and is confined between the body portion of the follower and the end of the barrel 24, said spring conressure on the along the rod 25.

Arranged on the support or. rod 25 to the left of the follower are a set or plurality of tabulator stops of novel construction. These stops, each designated as a whole by the reference numeral 29, are shown detached in 3 and 4. Each stop is bifurcated'having an inverted U-sliape and comprising two legs l30l and 31 and a cross bar 32 connecting the legs at their tops. vThe space 33 thus formed between the legs enables the stops to fit.over the rod 25 and into the notches 21 in the/stop bar 20. To facilitate the engagement of the stops with the bar 20 the lower ends of the legs 30 and 31 are v sharpenedjor provided with double bevels as illustrated; also the 'upper edge of the cross bar 32 is beveled to facilitate rentrance into the magazine. The top of t-he cross bar is formed with a notch 34 for eoperation with the ejector 3, while the leg 30 is formed with a rounded or circular'depression 35 for cooperation with the locking rod 22. The lefthand face of each stop at about the iniddle of the cross' bar 32 is formed with a depression 36 and` theopposite face is formed with a corresponding conical projection 37.

As will be plain form Figs. 1 and 4 the stops in the magazine are mounted face to face and the projection 37 of one stop fits into or engages with the depression 3G ot the next stop to theright, the projection 37 of said next stop in turn engaging with .the

depression 36 of the stop to the right of it` and so on. The spring-pressed follower 2b maintains the stops under pressure so that the devices 36 and 37 of the stops are inain- L tained interseated as described and. become cective to interlock the stops.

It will be understood from an inspection the left-hand stop 29 downward t-hroughthev slot 17 on to the stop bar 20. At the beginning of this downward movement the vprojection 37 acts as a cam against the depression 36 of the next. stop to the right, forcing said stop and all the other stops to yield slightly so that the projection 37 will disengage from the depression 36 as illustrated in Fig. 2. As soon as this projection 37.1ias passed below the cross bar 32 of the stop to the right, said stop, together with such other stops as Yremain in the magazine, will be straightened again on the supporting rod 25 by the spring pressed follower and after the' left-hand stop has been ejected far enough lso as to separate entirely from the stop to the right, the entire set of stops remaining ,in the magazine will be pushed lerftward by the follower until the next stop in turn is pressed against the face 19; The left-hand end ofthe floor plate 18 is notched out as indicated at 123a so as to provide a passage for the projections 37 during the ejecting operations. The follower or pressure device 26 is thus effective-to maintain the stops interlocked and also to force them leftward along the rod 25 so that they may be successively ejected. Said follower, it will be observedirom Fig. 1, is formed with a hole or opening 26JL which receives the projection 37 of the right-hand stop of the set, the construction enabling the follower toevenly engage with the right-hand face of said stop; also when all of the other stops have been ejected and this right-hand stop is pressed against the face 19 it will be held from accidental ejection by the engagement o-f its projection 37 with the lower side of the hole 26. When the stops are retracted within the magazine by the retractor 4 the projections 37 will act as cams against the stops within the magazine, forcing them to yield to the right to permit the'upward movement of the stop being retracted, which stop will finally interlock wth'the next stop to the right.l This operation is-repeat-ed until all of the'stops have been thus retracted.

Various changes of construction may be made without departing from the principles of my present invention. For example, in Figs. 5 and G there is shown a form of tabulator stop different from 29. The Figs. 5, G form designated asa whole by the reference numeral 38 is of the same general shape as the stop 29 comprising legs 39 and 40 andv iso a connectingr cross bar all provided with an ejector receiving notch 4Q. However. all ot the outside corners of said stop rc ronndeil as indicated at 43 to facilitate smooth and easy engagement` of the stop with associate parts duringy the ejecting and retracti operations. Also the upper and loner sin. i of the depression 4l, formed in the icc in for engagement with the locliin;M o-'l 151.". arc angularly inclined to each other instead ol' being parts or arcs o' a circular curve as at 35 in the prior construction. Bj: shaping the depression #t4 angnlarly as described the stop is adapted to engage inst. as ctliectively with the locking rod 22 but the discnggaging operation is facilitated because the upward pull against the lower side ol the notch siis nots-o direct as in the prior construction. Furthermore, it will be observed that the conical depression 3G and proicction 3T ot the prior construction. are replaced by a shallow rounded depression l5 and. a corre-- sponding rounded projection 4G in the Figs. 5,6 construction. These i'irojections and de` pressions or interlocking devices 45 and lf3 are found to be entirely ettectire for the purpose designed and also have the admi tage of a comparatively easy cih-engancment from and rengagenient with thc corre sponding devices ot adlacent stops. A hun ther important advantage of the last de scribed construction is that in nactice thc interlocking devices 4o, 46 may be formed hy pressure only, Whereas in the formation ot the conical or sharp interlocking devices flti and 37 of the prior construction. sonic ina chining is necessary which, of course. adds to the expense of prlwluction.

It will be observed that in both forms Slt) and 38 of the stop as describe/.l interlocking` with a stop magazine or holder of the con l struction or style illustrated in Figs. i" to l2, inclusive. This preferred construction coinprises essentially two parts t7 and 48. the part 47 being shown detached in Figs. 9 and 10 and the part 48 being similarly shown in Figs, 11 and 12. These two parte are made I of cast metal of suitable composition .and all machine work is eliminated. thus greatly rcduclng the expense of manufact-ure. The part 47 may be said to be the main part i i l comprising a body portion and a head 47 as neli as a. barrel portion 4?". The part 48 is Usl'iaped in cross section `nid forms the bottoni and sides of the magazine proper. The two parts after being; cast are ready for assemblingr without requiring any tinishing: or other work; ard when enihled or inten-:eatcd as iilnctratc- T and t? are secured ti'ngelhcr twg-frans n said screws passing through holer` in sides of the part il? and being; rcrciycd in tapped holesl formed in ings 49," on the pa rt i8. The twopart n'iaxiazii'ic after being assembled may be attached to the machine las For example to the carriage rail :i in the patent aforesaid) lay screws passing through slots 50. The part it? has guide-ways 5l and cast in its head t7. these guide-Ways' receiving respcctivcly the slidahlc ejector 3 and rciracior 4. and beine: found in practice. to provide for a smooth '2nd effective control and `guidance of these slidable parts or pieces. Further the barrel portion 47h is open at its right-hand end and Y is slightly flared to receive and hold by a drive fit a tapered nlug or end piece 53 which is rigid on the supporting rod 5t. said rod 54 cor-- responding ofith the rod of the Fig. 1 constriu-tion4 The rod 54V and plug 53 may lie and gueff-rably are of steel.

Various changes hesides those hereinbctore specified may he made without. departv ing troni my invention. f
